Ultrasonic Flow Switch
The Pulsar Mesaurement DFS 5.1 is a flow switch that utilises a doppler ultrasonic clamp on sensor. The control relay can be set to turn ON and OFF at any flow rate between 80 mm/s to 3 m /s (3.1 in/s to 9.8 ft/s). You can insert two links for separate ON/OFF set points or just one link for a Hi or Lo flow alarm. The relay actuation time delay can be set anywhere from from 0 to 80 seconds. The DFS 5.1 Doppler Flow Switch ultrasonic sensor is mounted on the outside of metal or plastic pipes. It continuously injects high-frequency sound through the pipe wall and into the moving fluid where acoustic pulses are reflected to the sensor from particles or bubbles in the fluid. Flow rates of most liquids can be accurately controlled including acids, caustics, lubrication fluids, chemicals, abrasives, wastewater, and sludge. There are no moving parts and no sensor maintenance is required.
Specifications:
- Best suited when no contact with media is preferred.
- No moving parts for high reliability
- Applications: dirty water, slurries, sewerage wastewater and corrosive media.
- Line sizes: 12.5 mm up to 4.5 m
- Power by 240VAC with 5A relay outputs and bar graph flow indicator.
